Just out of curiosity has it happen to anyone before? The thing is was that this morning I wanted to listen to my favor radio station for a few minutes that can only be recived from the car's radio for some reason, it's nothing but static with the radios inside my house. Anyway, I put the ignition on position i to listen the radio, but later I decided to check if my signal lights were all working so I put it on position ii. That's when the little display screen at the bottom only says disc, and after that it dissappars and becomes blank. I was never able to get it to repeat itself after that, so I'm not too worried. I just wanted to know why it did that.

 

it was prolly set to mpg or something and its "discovery" or decideding or some crap. aka calculating, so it prolly just didnt know what to display because it had no value

 

The control switch might be bad. I see it more on the S70's than on the 850's.
